Is Database-as-a-Service in your IT Services Catalog?

Are You Ahead or Behind the

Private Database Cloud Services or Database as a Service
(DBaaS) is no longer a new idea. In
fact, it is quickly becoming the de facto standard for development and testing
environments both on premises and in the public cloud. And while there are many use cases and
deployment options, overall database total cost of ownership and business
agility have benefited from a standardized approach to workload
management. Whether you are a DBA, an
operations manager, or a CIO, you are well aware that business-driven interest
in social, mobile, big data, and internet of things have caused an explosion of
development, data, and database workloads. The justification for database operations to pool resources and
standardize services has never been clearer – watch this
customer story (TRT1:30).

Today’s best practices in cloud architecture expect server
scalability, zero data loss resiliency, and most importantly workload security
and isolation through multitenancy. For database services, the architecture
would be incomplete if database operations did not also natively support
multitenancy. Initial approaches for DBaaS
were limited since they only relied upon virtual machines for workload
isolation and database provisioning. As general technology containers, VMs had
no intrinsic understanding of database operations, so they were unable to optimize
performance, scalability, and resilience as well as simplify database
administration efforts.

Today’s best practice for database cloud services overcomes
these limitations. The Oracle Private
Database Cloud approach is both revolutionary and elegantly simple. By engineering multitenant capabilities throughout
the Oracle database platform, the complete range of database operations and
administration can now be natively managed and
without the overhead of a virtual machine. Oracle’s Private Database Cloud guarantees isolation and leverages
Oracle’s strengths in reliability, scalability, security, and systems
management. Large database estates also benefit from a host of related
capabilities, such as cost-recovery reporting, self-service management, and
public cloud integration. You will find
that Oracle database platform is ideal for a standardized enterprise deployment
or cloud service, whether development/test or production – watch this
customer story (TRT2:17).

Oracle offers a reference architecture overview and Oracle
product mapping for DBaaS in a private cloud deployment model. The approach and guidance offered is the
byproduct of hundreds of customer projects and highlights the decisions that
customers faced in the course of their architecture planning and
implementations. Oracle’s advising
architects work across many industries and government agencies and have
developed standardized methodology based on enterprise architecture best
practices. Oracle’s enterprise architecture approach and framework are articulated
in the Oracle Architecture Development Process (OADP) and the Oracle Enterprise
Architecture Framework (OEAF).
